Temperature maintenance or freeze protection of pipelines and vessels in non-hazardous areas
The junction box for heating cable with mineral insulation is designed for the purpose of connection of mineral insulated (MI) heating cables to power network. The junction box could be mounted on a wall of a building or using a bracket directly on a pipe / vessel surface. The box enables connection of one mineral insulated cable heating section to power cable. The junction box is used as part of cable heat trace systems for pipelines and vessels in non-hazardous areas. The junction box design ensures moisture and dust ingress protection IP66 and high corrosion stability. The junction box is available with cable glands for connection of unarmored power cables. The installed terminal blocks ensure fast and safe connection of multi-core or single-core conductors. The boxes are available with screw clamp terminals as well as with push-in terminals.
